Eucomis bicolor is commonly called 'Pineapple Lily' because the flowers resemble a pineapple. This bulb is native to Africa and in the US is hardy in zones 8-10. My garden in Chicago is nowhere near the required zones so I grow it and then lift it in the winter and store the bulbs indoors in a cool and dry area.
I bought my first pair of these last year at the Menard's garden center because I couldn't resist the exotic looking flower. Apparently a couple of other people couldn't resist the exotic looks of this plant either because a few were stolen from my garden. I bought a couple of extra plants this year to replace the stolen bulbs.
Right now in the garden I have Pineapple Lilies growing in the ground and in pots and don't see a difference in growth rate or flowering. Last year I thought they looked too leggy in partial shade so this year I planted them in full sun and can see a huge difference. The flowers are more compact and the colors are a lot more vivid. Grow this if you want something different for your deck garden because they don't take up a lot of space in a pot.
I haven't noticed any special pollinators being drawn to this flower and the only bugs I see anywhere near it usually the odd fly or two. Even though they didn't attract any beneficial bugs to the flowers I still got plenty of seeds last year. If grown from seed the bulb can take between 2-5 years to reach blooming size. On the plus side I have not noticed these plants get attacked by any garden pests either.
When watering I think it may be best to avoid watering from above before the flower stem emerges. I had one start to rot recently and I think it may have been from water collected inside "the cup" the leaves form as they emerge. Also when storing them if the foliage hasn't died down completely hang it upside down or place it on newsprint or cardboard to absorb any moisture and rotate it. I made the mistake of leaving one in a plastic bag last year before the leaves all dried and I can't describe how horrible the scent of the rotting foliage is.
